Nope its just a regular battery pack I recommend using rechargeable batteries because eventually the battery pack starts to run out quicker and the rechargeable batteries last longer. I have so many default Xbox batteries but I can't use them any more with this controller because after a while for some reason it don't charge any more.
Run your macro controller with the play and charge kit it came with.plugged into the charging cable....it works best like this... My macro draws so much power the lights dim when it's not hooked up.
Ya Matt, even on a brand new fully charged battery, as soon as i take off the play n charge cable the lights dim out to some different color... It's really weird.
